ConnectX-5 VPI Adapter for 100GbE Networks

This NVIDIA ConnectX-5 VPI adapter card delivers EDR 100GbE connectivity for high-performance computing environments. It is designed for data centres and enterprise servers that require low-latency, high-throughput networking. The card supports Virtual Protocol Interconnect for flexible fabric deployment. It suits administrators building scalable InfiniBand or Ethernet clusters.

Practical Limits of 100GbE Deployment

Achieving full 100GbE throughput depends on compatible switch ports, cabling, and system bus bandwidth. The adapter requires PCIe slots with sufficient lane width and generation to avoid bottlenecks. Cable reach and power budget constrain topology choices in dense racks. Software tuning and driver support determine realised latency and CPU utilisation.

Questions about this item

Should I choose the EDR or the 100GbE version of the MCX555A-ECAT?

The MCX555A-ECAT supports both EDR InfiniBand and 100GbE Ethernet on the same adapter, so you do not need to pick between them.

What does the 100GbE rating mean when the card is installed in a server?

The 100GbE rating indicates the adapter can handle up to 100 gigabits per second of Ethernet throughput when connected to a compatible 100GbE switch and cabling.
